This petition was rejected

The Government e-Petitions Team gave the following reason:

Petitions need to call on the Government or Parliament to take a specific action. We're not sure exactly what you'd like the Government or Parliament to do.

We're not sure what aspects of the UK's net zero policy you want to see put to a referendum, or what action you would want the Government to take following any referendum. You could start a new petition calling for the Government to hold a referendum on dropping the UK's target of achieving net zero by 2050, if that's something you'd like to see happen.
